Here’s a yellow card warning for all of the anticipation of the United States’ World Cup match against Belgium this afternoon: Most Americans aren’t that excited, even if many of them are rooting on the home country.

Six-in-10 Americans – 61 percent – say they either have very little interest or no interest at all in the World Cup, according to a new NBC News/Wall Street Journal/Annenberg poll.

That’s compared with only 22 percent who say they have a “great deal” or “quite a bit” of interest. Another 17 percent say they have “just some” interest.

Among those with interest in the World Cup – either a lot or a little – the poll shows it’s clear for whom respondents are rooting: Team USA.
